Abstract (en)
[origin: EP0257935A2] A water separator is disclosed for removing water from a minute flow of gas/water sampled from a patients exhalation and prior to the gas being introduced into an analyzer. The separator comprises a housing with an inlet (l8), an outlet (38), and a pair of chambers (24, 30) in series through which the sample is drawn. The first chamber (24) has a pair of substantially closely aligned wall surfaces of predetermined narrow distance from each other such that the surface tension causes the liquid in the sample to adhere to the wall surfaces. As the sample progresses to the second chamber (30), the wall surfaces are further apart and thus the tension effect is broken and only the gas continues through the second chamber (30) to the separator outlet (38). A drain (40, 42) is located in the lower part of the first chamber (24) for withdrawal of the accumulated liquid from that chamber.
